Description:*Introduction* AISHELL-1 was developed by Beijing Shell Shell Technology Co., Ltd. It contains approximately 520 hours of Chinese Mandarin speech from 400 speakers recorded simultaneously on three different devices with associated transcripts. The goal of the collection was to support speech recognition system development in 11 domains, five of which are include in this corpus: Finance, Science & Technology, Sports, Entertainment, and News. Participants read 500 sentences covering the domains; sentences were chosen for their speech and phonetic characteristics. Speakers were recruited from different accent areas across China, including North, South and Yue-Gui-Min regions. There were 214 female speakers and 186 male speakers, constituting 53% and 47% of the database, respectively. Additional demographic information about the participants is included in this release. *Data* Speech was recorded in a quiet indoor environment on a high fidelity microphone and two mobile phones (Android and iOS). All speech is presented as 16-bit flac compressed wav files; the microphone speech sample rate is 44.1kHz and the phone speech sample rate is 16kHz. Each speech file ranges from approximately 1 second to 14 seconds in length. Transcripts are stored as UTF-8 encoded plain text files and are not time-aligned. *Samples* Please view the following samples: * Microphone * Android * iOS * Transcript *Updates* None at this time.
